I am using QGIS 3.2.3. I am trying to do some simple actions. Selecting by attribute and exporting to shapefiles. I am using a OSM file as a source which is barely 60MB. But for some reason the process is incredibly slow (as in, it runs for twenty minutes and only reaches 5% of the export). When I look at my task manager QGIS is only using between 5-10% I suspect this is not much, but I don't know how to increase it (or even if I should.) Should I make it use more CPU? Or should I find another way to speed it up?
